Back Gears for the Gingery Lathe

Description

"Back Gears" are just what their name implies. A set of gears mounted at the back of the headstock on a lathe. Their purpose is to allow the lathe spindle to rotate at slower speeds while at the same time delivering greatly increased torque. One operation that really benefits from those slower speeds is thread cutting, especially if you are a beginner. With back gears, your lathe not only becomes capable of doing a better job of cutting threads, it also allows for increased drilling capacity, larger hole boring and larger diameter facing. Simply put, back gears will enable your lathe to be used at its maximum strength and capacity. If you have built the other Gingery projects in the "Metal Working Shop from Scrap" series, you have all the necessary tooling for the job. Here in this booklet, Marvin provides you with the step by step instruction beginning with the patterns, molding procedure, machining the castings and finally fitting the individual parts on the Gingery lathe. Included are many detailed drawings and photos that help make the project easy to understand. And for a final touch of class, Marvin shows you how to add a change gear cover, back gear cover and front cover to your Gingery lathe. This is a truly delightful project. If you have built or are planning to build the Gingery lathe, consider adding back gears. You will be glad you did. Review: Good book - This is a good book with some great information. The only one of its kind that I've found if you want better control over the speed of the spindle on your Gingery lathe. I feel that it's not quite as clear as Gingery's writings though. I had to read parts of it several times to fully understand how the mechanism is supposed to work. That could just be me though. It's only 56 pages long and while there are gears involved there's no discussion on how to cut those gears. Make sure you've read Gingery's 6th book, The Dividing Head & Deluxe Accessories, before you buy this book. If you can't handle the projects in that book you'll never be able to complete the projects in this book. Ideally, if you're interested in this book you've all ready been through the entire Build Your Own Metal Working Shop From Scratch series or are planning to go through them. I do like the way Mr. Guthrie changes the drive on the lathe. It makes it look much more neat and professional. It's a nice book with some good information. I plan to include these back gears in my lathe when I build it. Since it's only 56 pages though it could be a little cheaper though. The Dividing head book is only $9 and it's three times the length of this book. Like I said this is the only book I've found with this type of information for the Gingery lathe so... Review: Great book! - An outstanding book for making back gears. Great step by step instruction and explanation. Best ever! This is a great buy for those wanting to turns threads.
